How to ensure high availability of apisix when apisix as a the Front gateway

[carverLiu]

i am very pleasureto meet apisix ，and ask some question for high availability of apisix
1、First ,apisix as a the Front gateway , when the apisix service down ,What should I do for it?
i think may be i can use keepalived and Vip to listen the master ,when the master down , the slave can get the message by heartbeat and the slave become the matser 。
but the idea drive other problem, the apisix can loss some traffic When the slave node listens to the downtime of the master node，may be 2~4s 。
SO.....I hope dear friends can give some other advise to slove this problem

中文：我们的业务需要使用apisix作为前置一级网关，当apisix 宕机了，我如何保证当前业务的可用性呢？
目前想到的是使用keealived+vip实现主从热备，故障自动转移，slave 成为master ，虚拟IP漂移地址到slave。
但是这种方法，故障自动恢复的过程需要2~4S恢复服务，导致这段时间流量丢失，各位大大有什么建议嘛？
